Any way to adapt a Takahashi Mamiya 645 mount?
Posted 06 December 2012 - 02:44 PM
I have a Takahashi Mamiya mount and I would like to adapt it to use on a standard 2" tube. I realize that I would get some or perhaps a lot of vignetting on my Phase One back but would like to give it a shot as long as I don't have to tear up the mount adapter itself to try?
The Tak Mamiya mount adapter is a standard Mamiya camera mount on one side but has male threads on the other side with a diameter of approx 71 or 72 mm. Not sure of the thread size.
Any feedback would be greatly appreciated!

Precise Parts could make an adapter for you:
Yes your image circle will be reduced to the smallest I.D. of your focusing system.
Which scope are you trying to put it on?

I considered cementing the draw tube to the adapter with JB Weld but that would basically ruin the adapter and the end goal is to mate it with a TSA-102 once funding permits.
I like the idea of having these folks build a custom adapter. It would have to be a female 72mm Tak on one end to a 2" drawtube. I would think I would want it to be a few inches long so I could experiment with correct image plane distance by simply moving the tube in and out. I have not been able to locate anything with these basic requirements.
Thanks for the tip, I'll give these guys a call and go from there,

I do like the idea of the MF lenses since the Pentax 67/645s are cheaper than current EOS lenses.
Maybe it will be the next step.
